Top Accessories For Your 2021 Subaru WRX STI
Hey Subaru enthusiasts! If you're the proud owner of a 2021 Subaru WRX STI, you already know you've got a beast of a machine. But why stop there? Let's talk about how to take your STI to the next level with the right accessories. This isn't just about looking good; it's about enhancing performance, protecting your investment, and making your driving experience even more thrilling. We're diving deep into the must-have accessories that will make your 2021 WRX STI truly stand out from the crowd. So, buckle up, and let's get started!
Performance Enhancements: Unleash the Beast Within
When it comes to performance enhancements, the 2021 Subaru WRX STI is already a powerhouse, but there's always room for improvement, right? These upgrades aren't just about adding power; they're about refining the driving experience, improving handling, and making your STI even more responsive. Let's explore some of the key areas where you can make a significant impact.
Exhaust Systems: Hear the Roar
Upgrading your exhaust system is one of the most popular modifications for any performance car, and the WRX STI is no exception. A high-quality aftermarket exhaust system can significantly improve exhaust flow, which translates to increased horsepower and torque. But it's not just about the numbers; it's about the sound! Imagine the deep, throaty rumble of a performance exhaust echoing as you accelerate. Brands like Invidia, Cobb Tuning, and Borla offer fantastic options for the 2021 STI. When choosing an exhaust, consider the material (stainless steel or titanium), the diameter of the piping, and the muffler design. A cat-back system, which replaces the exhaust system from the catalytic converter back, is a common choice for a balance of performance and sound. A turbo-back system, which replaces the entire exhaust system, offers even greater gains but may require additional tuning.
Intake Systems: Breathe Easier
Just like a high-performance exhaust system helps your engine exhale, a performance intake system helps it inhale. The factory intake system on the WRX STI can be restrictive, especially when you start adding other modifications. An aftermarket intake system replaces the factory airbox and filter with a less restrictive design, allowing your engine to breathe easier and more efficiently. This can lead to noticeable gains in horsepower and throttle response. Popular brands like AEM, Mishimoto, and Perrin offer intake systems specifically designed for the 2021 WRX STI. When selecting an intake, consider whether it's a short ram intake (SRI) or a cold air intake (CAI). SRIs are easier to install and provide a more aggressive sound, while CAIs draw air from outside the engine bay, resulting in cooler intake temperatures and potentially greater power gains.
ECU Tuning: The Brains of the Operation
Once you've upgraded your exhaust and intake systems, it's crucial to ensure your engine is running optimally. This is where ECU tuning comes in. The engine control unit (ECU) is the brain of your car, managing various parameters like fuel delivery, ignition timing, and boost pressure. A professional tune can remap these parameters to take full advantage of your new modifications, resulting in significant power gains and improved drivability. Cobb Tuning's Accessport is a popular choice for WRX STI owners, allowing you to flash pre-loaded maps or work with a tuner to create a custom map tailored to your specific modifications. Remember, a proper tune is essential to ensure the longevity of your engine and prevent potential issues caused by running too lean or too rich.
Aesthetic Upgrades: Style and Substance
Okay, guys, let's be real – looking good is part of the game! While performance is key, the aesthetic upgrades you choose for your 2021 WRX STI can make just as big of a statement. These enhancements are all about personalizing your ride and making it a true reflection of your style. From subtle accents to bold transformations, the possibilities are endless.
Wheels and Tires: The Foundation of Style
The wheels and tires you choose can dramatically change the look and feel of your STI. Upgrading to a set of lightweight alloy wheels can not only enhance the appearance but also improve handling and acceleration by reducing unsprung weight. Popular brands like Enkei, Volk Racing, and Work offer a wide range of stylish and performance-oriented wheels for the WRX STI. When selecting wheels, consider the size, offset, and style that best complements your car's aesthetic. Tires are just as important as wheels, so choose a set that matches your driving style and the conditions you typically encounter. Performance summer tires like Michelin Pilot Sport 4S or Bridgestone Potenza RE-71R can provide exceptional grip and handling on the street and track, while all-season tires offer a more versatile option for daily driving.
Exterior Trim and Body Kits: Make a Statement
Adding exterior trim and body kit components can give your WRX STI a more aggressive and unique look. A front lip spoiler, side skirts, and a rear diffuser can improve aerodynamics and enhance the car's sporty stance. A rear wing or spoiler can add a touch of motorsport flair while also providing functional downforce at higher speeds. Popular materials for body kit components include polyurethane, fiberglass, and carbon fiber. Polyurethane is a durable and flexible option that can withstand minor impacts, while carbon fiber is lightweight and adds a high-end aesthetic. When choosing exterior trim, consider the overall style you're aiming for and ensure the components fit well and complement the car's lines. Brands like APR Performance, Varis, and Chargespeed offer high-quality body kits and trim pieces for the WRX STI.
Lighting Upgrades: See and Be Seen
Upgrading your lights is a great way to improve both the appearance and safety of your 2021 WRX STI. LED headlights and taillights offer a brighter, more modern look compared to the factory halogen units. LED daytime running lights (DRLs) can enhance visibility and add a stylish touch. Fog lights can improve visibility in adverse weather conditions. Consider adding aftermarket headlights with projector beams for improved light output and a sharper cutoff. Smoked or tinted taillights can add a subtle yet aggressive look. When upgrading your lights, ensure they comply with local regulations and don't compromise visibility.
Protection and Practicality: Safeguard Your Investment
Let's not forget about protecting your prized possession! Protection and practicality accessories are essential for keeping your 2021 WRX STI in top condition for years to come. These upgrades might not be as flashy as performance or aesthetic enhancements, but they're crucial for preserving your car's value and ensuring it stays looking its best.
Paint Protection Film (PPF): Shielding the Shine
Paint Protection Film (PPF), also known as clear bra, is a transparent film applied to your car's paint to protect it from scratches, chips, and other damage. PPF is a must-have for any car enthusiast who wants to keep their paint looking pristine. It's especially beneficial for high-impact areas like the front bumper, hood, and fenders. PPF is available in various thicknesses and finishes, with self-healing properties being a popular feature. Brands like XPEL and 3M offer high-quality PPF that can provide years of protection without detracting from your car's appearance. Professional installation is recommended to ensure a smooth, seamless finish.
All-Weather Floor Mats: Keep It Clean
The interior of your car is just as important as the exterior, and all-weather floor mats are a simple yet effective way to protect your carpets from dirt, mud, and spills. These mats are typically made from durable rubber or plastic and feature raised edges to contain messes. They're easy to clean and can be removed for washing. Brands like WeatherTech and Husky Liners offer custom-fit floor mats specifically designed for the 2021 WRX STI. Investing in a set of all-weather floor mats is a small price to pay for the long-term protection of your interior.
Car Covers: Shield from the Elements
If you park your WRX STI outdoors, a car cover is essential for protecting it from the elements. A high-quality car cover can shield your paint from sun damage, rain, snow, and dust. It can also help prevent scratches and dings. Car covers are available in various materials, with waterproof and breathable options being ideal for outdoor use. Consider a custom-fit cover for the best protection and fit. Regularly using a car cover can significantly extend the life of your paint and keep your STI looking its best.
Interior Upgrades: Comfort and Convenience
While the WRX STI is known for its performance, the interior is where you'll be spending your time, so let's talk about interior upgrades. Enhancing comfort and convenience inside the cabin can make your driving experience even more enjoyable. These upgrades can range from subtle touches to complete overhauls, depending on your preferences.
Seat Upgrades: Comfort and Support
The factory seats in the WRX STI are decent, but upgrading to aftermarket seats can provide significantly more comfort and support, especially during spirited driving. Performance seats often feature deeper bolsters to hold you in place during cornering and can be customized with various materials and colors to match your interior. Brands like Recaro and Sparco offer high-quality seats that are both comfortable and stylish. When choosing seats, consider the level of support you need, the material, and the overall aesthetic.
Shift Knobs and Short Shifters: Enhance the Connection
For a more engaging driving experience, consider upgrading your shift knob and shifter. An aftermarket shift knob can provide a more comfortable grip and a sportier feel. Short shifters reduce the throw between gears, allowing for quicker and more precise shifts. A combination of a weighted shift knob and a short shifter can transform the feel of your STI's transmission. Brands like Perrin and Cobb Tuning offer shift knobs and short shifters specifically designed for the WRX STI.
Audio and Electronics: Tune In and Tech Up
Upgrading your audio and electronics can make your daily drive more enjoyable. Consider adding a new head unit with Apple CarPlay or Android Auto for seamless smartphone integration. Upgrading your speakers and amplifier can significantly improve sound quality. Adding a subwoofer can provide deeper bass and a more immersive listening experience. A dashcam can provide valuable evidence in the event of an accident. Adding a boost gauge or other performance monitoring tools can help you keep an eye on your engine's vitals. The possibilities are endless when it comes to audio and electronic upgrades.
